Thus it can be very dangerous when there is an explosion—or in the case of Fukushima, an earthquake—at a nuclear plant, and some of the radioactive atoms escape into the surrounding air, water or soil, causing contamination.The decay of radioactive materials is a random process, kind of like flipping a coin or rolling a die.This additional information may also help teachers to generate additional follow-up questions and extensions of this project.1.
You may wish to bring in an artifact to show or a picture of the artifact you want your class to image to be.
Your students may be familiar with the Dead Sea Scrolls, a famous artifact dated using carbon-14 dating.
Some types of radiation surround us every day and are perfectly safe, such as radio waves and visible light; other types, such as x-rays and gamma rays, can be dangerous to humans.
The types of atoms used as fuel in nuclear reactors can produce such dangerous radiation, which is why it is very important to keep the fuels safely contained.
Credit: George Retseck Key concepts Energy Radioactivity Exponential decay Odds Introduction One way of creating energy is with nuclear reactors.
These plants are generally safe, but occasionally there are accidents in which dangerous radioactive material escapes.
What is the process of carbon dating, and can the results be believed?
Through the use of an interactive Web site, students will learn about C-14 and C-14 dating.
This lesson can be used as an introduction to radioactivity.
Students should have familiarity with the scientific notation and the units milli, micro, and nano.
To do this lesson and understand half-life and rates of radioactive decay, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.
